There's no getting around it the cost of living is increasing.
So for most of us that means unfortunately higher running costs from fuel.
One answer is to go All-Electric which for some may work but as of right now
whether that be due to upfront cost of the actual car
or infrastructure, it might not be suitable for everyone.
So if you fancied upgrading your car to one of the latest models
how about shopping for one of the most economical as well?
Giving you more miles per tank of fuel!
And that is exactly what we're going through today now I've spent a good
couple of hours going through every single engine that Mercedes-Benz make in the UK
and paying close attention to all the brochures with their WLTP stats
and I've found the top three petrol cars and the top three diesel cars.
So before we jump into that...what does WLTP stand for?
That stands for Worldwide Harmonised Light Vehicles Test Procedure.
And is basically an independent test done on every single car
showing you the best MPG that they can achieve.
Compared with NEDC tests years ago, NEDC tests did:
'Combined', 'Extra Urban' and 'Urban' tests and to be honest they weren't very
realistic so this is why on these tests you had to kind of deduct about 10 / 15 or even
sometimes 20 MPG to show you what the car can actually do which wasn't really fair.
WLTP now is the new standard and it shows you what the cars can achieve with all four
wheels on the floor and what you and I can achieve in the car when driving.
So with all that in mind let's start with the top three most economical petrol models!
Now in 3rd place it's no surprise that one of Mercedes-Benz's most
aerodynamic production cars is here which is the CLA coupe and Shooting Brake.
Yes aerodynamics play a huge part in overall engine efficiency
so these cars with their 180 and 200 engines get an MPG figure of 45.6.
Very nice!
However this is achieved of course by its aerodynamics and its drag
coefficient factor is 0.23 meaning it cuts through the air just like butter.
And you genuinely notice it on the road! In fact this car was based on the A-class which
is one of Mercedes-Benz's best-selling models but offering a more sloppier curvier look.
Featuring that MBUX as its multimedia system with the very clever
Hey Mercedes voice assistant, it's certainly one to consider.
Up next in 2nd place is the Mercedes-Benz B-Class and in a weird turn of events,
despite it not looking as aerodynamic as a CLA it beats it with a 46.3 MPG figure on its WLTP test.
It also features in some models a thing called an Easy-Pack Tailgate which is an electric boot
which is one up on the CLA coupe for sure but it does feature that kind of more spacious interior
and also a raised driving position as well so it's easier to get in and out.
Also features the MBUX system as well just like the CLA so you've got that pretty cool....
Hey Mercedes!
Car: How can I help?
Voice assistant!
And then finally guys in 1st place on the
petrol engines is the Mercedes-Benz A-Class as the most economical!
Now yes I know this one here is the A45 S so this particular engine won't fall into that category
but the A 180 and A 200 variants with that 1.3 L engine get that 47.9 MPG
making it the most economical petrol engine that you can buy currently.
It's also available in a saloon just in case you want to go for a slightly different body shape
but most importantly it is one of Mercedes-Benz's best-selling models
probably because of that reason to be honest!
It first came out in Summer 2018 where I actually got the opportunity to see it
pretty much before anybody else which I was super fortunate to do
and I think even then I didn't even take into consideration how futuristic the
interior looked with those double widescreen displays which were taken straight from the
Mercedes-Benz S-class which is one of the flagship models that Mercedes-Benz make.
And in a weird turn of events actually had more gadgets than that actual car
so the A-class definitely was a trendsetter for years to come.
So topping out at 47.9 MPG on petrol how does diesel fare up?
Well let's have a look!
Now in 3rd place on the diesels it's the Mercedes-Benz B-class so yes
it's actually made the top 3 in the petrol engines and top 3 in the diesel engines as well.
So this is the 2.0 L diesel engine in the B-class range and it achieves a WLTP
figure of 55.4 mpg making it the top 3.
Now some of you may be wondering is a diesel still okay to use in 2022?
Well I'd like to cover that very quickly before moving on to the 2nd place winner in the diesels!
Now diesel technology has come a long long way from years and years ago,
most diesels now have this thing called AdBlue.
Now yes these are both separate tanks just to be clear,
so diesel goes in diesel and AdBlue goes in the AdBlue section just here.
Now AdBlue is the name of the actual liquid as well that goes in and it basically reacts with
the exhaust system or some of the gases in it removing nitrous oxide from the exhaust tailpipe.
In terms of top-ups if you do high mileage in a year then you may need to top this up but in most
cases it should last to your service and fun fact of the day, in some models of modern cars
out there today if you have AdBlue, it actually produces less nitrous oxide than a petrol engine!
Well the A-Class won the most efficient petrol engine out of any Mercedes-Benz you
can buy with its 1.3 L engine when it comes to diesel it actually comes in 2nd place.
Now this is from its 2.0 L diesel engine and it produces 60.1 MPG which is really
really good considering it's gone over that 60 MPG mark.
Not many cars can do that on their WLTP tests so if that's second place who's in first place?
So then guys in 1st place we have a car that can achieve
61.4 MPG on its WLTP test which to be fair just literally scrapes the
margin on the A-Class so they're really really close to each other but 61.4 MPG!
The highest performing most efficient mercedes engine goes to the C-Class
2022 model which is insane that's a very very high number for a WLTP test.
Now I have actually had the awesome opportunity to see this car last year, I went up to Mercedes-Benz
World had a little play on its multimedia system which actually has a brand new multimedia system
called I think it's NTG 7.0 it's called internally but I like to call it MBUX V2.
So it's got a kind of portrait styled screen, new gadgets, specification and of course
obviously those gadgets must extend to the engine as well getting that high MPG figure.
Now if you want to check that out I'll link it at the end of the video now of course sadly due to
the semiconductor shortage I haven't actually seen a UK spec version of that car just yet.
So I'm sure it's on its way!
We'll just kind of have to watch this space but when I do get my hands on one
i will cover a detailed video about that car and its multimedia system as well.
So do watch this space!
Keep an eye on my channel so when I do get my hands on one, I will cover it.
But yes guys there we have it that concludes this week's video on the most
efficient Mercedes models that you can buy!
So if you want to know more about that C-Class check out this video right here!
Because this one is going to take you straight to the video that I did last
year where I had kind of like a first impressions of the C-Class.
It was really really cool to see so well worth a watch!
But again huge shout out to Sandown Mercedes-Benz as they provide access to all the cars you see
so it'd be very difficult to do it without them but thanks so much for watching
we'll see you next week!
